I no longer work for IBM so I can't be sure, but I'm not aware of virtio support in AIX 7.1.
As said in another comment, the "Unimplemented SPAPR hcall 0x00000000000002b8" trace reflects that QEMU doesn't implement PEM (Partition Energy Management) as described in section 14.14 of LoPAPR. I can't tell if this causing the crash of the AIX kernel, but I'd suggest you try with AIX 7.2. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1846816 Title: Booting error on AIX 6.1 "Illegal Trap Instruction Interrupt in Kernel"" Status in QEMU: New Bug description: # ls -ltr total 8750584 -rw-rw-r-- 1 linux linux 4274997248 Oct 4 18:33 AIX.vol1.iso -rw-rw-r-- 1 linux linux 4293888000 Oct 4 18:45 AIX.vol2.iso -rw-rw-r-- 1 linux linux 391485440 Oct 4 18:50 AIX.vol3.iso -rw-r--r-- 1 root root 204608 Oct 4 19:00 AIX61.img # qemu-system-ppc64 -cpu POWER8,compat=power7 -machine pseries -m 8192 -serial mon:stdio \ > -drive file=/qemu/AIX61.img,if=none,id=drive-virtio-disk0 \ > -device virtio-scsi-pci,id=scsi -device scsi-hd,drive=drive-virtio-disk0 \ > -cdrom /qemu/AIX.vol1.iso \ > -prom-env boot-command='boot cdrom: -s verbose' VNC server running on ::1:5900 qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ibs=workaround SLOF ********************************************************************** QEMU Starting Build Date = Jul 3 2019 12:26:14 FW Version = git-ba1ab360eebe6338 Press "s" to enter Open Firmware.
